It was the first Celebrity Big Brother series to be shown in the 16:9 widescreen format. The series saw the return of Jade Goody, who became a celebrity after appearing on the third regular series of Big Brother in 2002, arriving with her boyfriend and mother, it was the first series where family members could enter the house together. On 16 January 2007, this series had attracted the largest ever number of public complaints to the UK broadcasting watchdog Ofcom about a Big Brother series. The complaints received detailed concerns that housemate Shilpa Shetty had been subjected to bullying. Goody, Danielle Lloyd and Jo O'Meara's behaviour towards Shetty sparked widespread anger and demonstrations in India, where the alleged racism was reported on the news, and led Big Brother's main sponsor Carphone Warehouse to suspend its sponsorship of the show. As of 19 January 2007, a Channel 4 spokesman agreed that participants should be made aware of the controversy, probably explaining the recent explanations and apologies tendered by the housemates and their complete lack of surprise after learning about the latest eviction.
